Warning Signs

Warning Signs by Caledonia Signs - Trade Only Supplier

BS EN ISO 7010:2020 was developed to provide consistency in safety sign design across the UK and EU. By using ISO 7010 pictograms and symbols, our warning signs provide universal recognition - this means that a warning symbol in the UK will look the same as it would in all European countries.

Warning signs advise viewers of potential hazards within an area. They incorporate a yellow triangle (black border) with a black pictogram inside. Supplementary text must be black on a yellow background and must lead with "Danger, Warning or Caution".

Danger: should be used only for hazards which may cause serious injury or death. Warning: should be used for hazards which could cause mild to severe injury. Caution: should be used for mild hazards only.

We provide a wide range of warning signs & products covering virtually all types of hazards - from asbestos to water
